make does modify the source tree

[Olaf Hering <olh at suse dot de>]

Hi,

the current gcc-3_1-branch does not compile when the source tree is
owned by someone else:

gcc -c -DIN_GCC -DCROSS_COMPILE   -O2 -fsigned-char -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long  -DHAVE_CONFIG_H -DGENERATOR_FILE    -I. -I. -I/heim/olaf/usb/gcc/source/gcc-3_1-branch/gcc -I/heim/olaf/usb/gcc/source/gcc-3_1-branch/gcc/. -I/heim/olaf/usb/gcc/source/gcc-3_1-branch/gcc/config -I/heim/olaf/usb/gcc/source/gcc-3_1-branch/gcc/../include /heim/olaf/usb/gcc/source/gcc-3_1-branch/gcc/genconstants.c -o genconstants.o

source tree is owned by user "olaf", the user "usb" does the build in
another directory.

build script looks like that:

mkdir gcc-first
cd gcc-first

        CFLAGS="-O2 -fsigned-char" ${BUILD_SRC}/gcc-3_1-branch/configure \
        --target=i686-linux \
        --enable-languages=c,c++ \
        --disable-nls \
        --disable-shared \
        --with-headers=$BUILD_INC \
        --prefix=${INSTALL_DIR}

        make $MFLAGS || exit 1
        make check || true
        make install  || exit 1
cd ..

Host is powerpc-linux, target is i686-linux.


Is this an unsupported configuration or a bug in the build process?
